Study Notes

Nutrients and Their Functions

Vitamins enable chemical processes in the body, critical for various metabolic functions.
Minerals are essential as they become part of the body’s structural systems, supporting overall health.
Carbohydrates do not contain more kilocalories than proteins, they provide energy but are lower in calorie density.
Lipids (fats) supply a concentrated source of fuel for the body, playing a significant role in energy provision.
Fats provide the most energy per gram compared to other macronutrients.
Proteins are the most significant energy source for humans, but their primary roles include growth and repair rather than energy supply.
Plant fats provide greater than 4 kilocalories per gram, indicating their high energy content.

Nutrient Classes and Energy Yield

Water does not provide energy, contrary to misconceptions regarding its role in nutrition.
Alcohol is not classified as an essential nutrient despite its energy-yielding properties.
A kilocalorie measures heat energy, quantifying the amount of energy from food.

Energy and Caloric Content

Bleu cheese dressing containing 23 grams of fat yields 207 kilocalories from fat.
A meal of a cheeseburger, fries, and a shake provides 1,120 kilocalories with specific energy contributions from carbohydrates (48% of total) and protein (13%).

Nutritional Concepts and Guidelines

Freshman 15 describes the typical weight gain experienced during the first year of college, often cited as 15 pounds.
The leading nutrition-related cause of death in the U.S. is heart disease, underscoring the importance of healthy eating.
Essential nutrients must be consumed as they cannot be synthesized by the body.

Dietary Recommendations

Dietary Guidelines for Americans recommend limiting calories from saturated fats and added sugars to prevent chronic diseases.
Emphasizing a variety of foods is vital for achieving good nutritional status.
Estimated Energy Requirements (EER) estimate caloric needs based on age, gender, weight, and activity level.

Nutrient Density

Nutrient density refers to the ratio of a nutrient in food relative to its kilocalories, emphasizing that nutrient-rich foods can improve diet quality.
For example, orange juice is more nutrient-dense for vitamin C than apple juice due to its higher vitamin C content relative to calories.

Dietary Assessments and Evaluations

Dietary assessment includes methods like recalling food intake over the past 24 hours to evaluate nutritional status.
Biochemical evaluations provide insights into nutrient deficiencies through blood tests.

Moderation and Balance

The principle of dietary moderation involves adjusting intake based on previous meals to maintain balanced nutrition.
Overnutrition may occur when consuming excess kilocalories beyond energy needs, leading to potential health issues.

MyPlate and Food Labeling

According to MyPlate, eggs fit into the protein food group, emphasizing the role of diverse foods in a balanced diet.
Understand food labeling requirements, including the mandatory display of nutrients that have established RDA values.

Healthful Eating Practices

Nutrient-density guidelines encourage selecting foods that maximize nutrient content relative to calorie count.
Limiting saturated fatty acids to less than 10% of total calories supports cardiovascular health.

Body Measurements

Anthropometry involves body measurements like height, weight, and body fat to assess nutritional status and health.
The Recommended Dietary Allowance (RDA) serves as a benchmark for daily nutrient intake to promote health.
